I want IPv6, but…

Ok, I am not a big fan of Teredo, a tunneling technique that rides IPv6 inside UDP packets over IPv4, but there are times when it is required. Let’s first start with a time when it should not be used and that is when you are an authorized user on an enterprise and need IPv6. In this case call your IT department.

When should it be used? Anytime that you need to connect to IPv6, but the local switch, upstream router, network firewall or ISP does not support IPv6. Here are methods to enable IPv6:

Windows XP – enable Ipv6

Vista, Windows 7 and Window 8 – IPv6 is enable by default; your IT department might have disabled it by default in all cases. Call your IT department.

Linux Ubuntu/Debian – “sudo apt-get install miredo” is enough to have IPv6 connectivity. There is no configuration needed.
